They caused me to get drug induced lupus which carried on long after the drug was stopped, it attacked all my connective tissue and severely wasted all muscles and real bad neuropathy in face/ hands and feet and to many other symptoms to mention. I believe all antibiotics have the ability to cause this just not quite as severe as the Fluroquinolones. People trust doctors to much they should talk to the people that have used there toxic drugs before you go ahead. And after all that the treatment failed. I still have MAC and whole lot of pain disabilities on top thanks to antibiotics.
